Another way we could tell the difference is if the def
statement used a different protocol for making bindings
than assignment.
Suppose a def statement used in a class body called
__defitem__, if it exists, instead of __setitem__. Then
the metaclass would be able to do different things for
defs and assignments.
Well, some assignments could be for non-enumeration items, once you
start allowing EnumItem in the list. Some method of grouping
enumeration items, or grouping non-enumeration items would solve the
problem.
class Color( Enum ):
Enum.__enumerationItems__(
red=1,
green=2,
blue=3,
)
# other methods and assignments
